Title: Printed wiring board
Inventor: KAWAKAMI SHIN
IPC: C09D5/24
Filed: 1988-11-02
Abstract: PURPOSE:To connect conductors on both upper and lower surfaces completely by using expandable conductive paste as conductive paste filled into a through- hole and conducting circuits on both surfaces. CONSTITUTION:Expandable conductive paste 7 is employed as conductive paste filled into a through-hole 6 penetrated through an insulating substrate 1. The conductive paste 7 is filled from one surface through silk screen printing, etc., and the conductive paste is heated up to a temperature, where a foaming agent in a compound is decomposed, and foamed while the conductive paste is irradiated with ultraviolet rays and cured. Accordingly, the feed of the paste at the time of silk screen printing is made the same as conventional devices, and the paste is expanded in the through-hole and brought into contact completely with conductors on both surfaces, thus preventing bridging and defective continuity.

Title: Method for improving depth-direction resolution buried object searching device
Inventor: WATANABE YASUSHI
IPC: G01S13/88
Filed: 1988-11-02
Abstract: PURPOSE:To improve the resolution of a buried object searching device in a depth direction by removing ringing associated with a reflected waveform by processing a receiving waveform by utilizing the receiving waveform and the differential waveform and moving average waveform of the receiving waveform. CONSTITUTION:The waveform f(t), f'(t), and F(t) in the figure respectively represent a received waveform by only fetching reflected echoes from an objective target, the differential waveform of the waveform f(t), and moving average waveform of the waveform f(t). When the three kinds of waveforms are added to each other after they are appropriately multiplied by coefficients and giving appropriate phase differences to them, the waveform G(t) shown in the figure is obtained. The calculating range of the moving average waveform is from a minimum of about 10 points to a maximum of about the length of a reflected waveform and the multiplying coefficient of the moving average waveform is about 1/5 to five times of the value required for making the receiving waveform equal to a peak value. Similarly, the phase differences are about the length of the reflected waveform in both the maximum delay and advance. The waveform G(t) thus obtained is improved in the minimum resolution in the depth direction for searching.

At the same time, a part corresponding to the standard value is blinked on a segment 404 at the same time. Copy density correction keys 405 and 408 are operated properly so that an image of the standard original has proper density. Consequently, the developing bias is easily adjusted without using any measuring instrument.
